My invention relatesto water columns, and has for its object to provide anovel construction wherein a curved and entended delivery pipe preferably'of sheet metal or other relatively'light substance is attached to the upper end of a vert'ical standpipe in I such manner that the delivery pipe, and the discharge spout lcooperating therewith, are

capable of rotation upon the 'standpipe, abouta vertical axis while the standpipe itself remains stationary. 1 Another "important object ofimy invention is to providein combination with said rotating'delivery pipe means for positively locking the dischargespoutwhen' the same f tioned-over ring14 isa top-ring 17-havinga depending annular flange 18"which 'entirely surroundsthe ring 14' and has an in- "sidegroove 'or ball" race 19 corresponding throwing back of the deliveryipipe and -b'eing subject to readyrelease'by an operative from the tenderofa locomotivef A further ob ect of my invent on is to provide 1n com and discharge spout,'-" valvecontrolling means. rotatable therewith and operated In the drawings, illustrating the .appli'caf construction shown inFi'g's. 3, .4, and8 to be; highly efficient and entirely satisfactory for. that purpose. the; balls "being' insertedinto V i r tion of my invention in one form, p I Figure Lshowsasule elevatio of aw'ater column embodying lnvention with the delivery pipe-and discharge spout in inoperative "position parallel with the tracks.

I have found the the assembled grooves; through an opening 28 in flange 18 normallyclosed by a plug -29 As best shown in Figs 3, 5, and "8, the" top ring 17 is formed with downwardly extending portion adaptedflto comebe tween stand ring 14 panda milled surface 31 on standpipe section 13, and the top ring rings--32 with any desired, pressure by means oflnutson studs 35., This forms-a watertight jointbetween'top ring 17' and standpipefsectioneli'l, and as 'the top ringprovides the-support for the laterally extended top pipe-hereinafter referred"to,.it will be apparentth'at this'arrangement forms a watertight joint between a hired vertical standpipel'and' a laterally extended top pipe: rotatively supported thereon. It isimportant in such a'cons'truction that the stuffing box be easily accessible for maintenance or re packing. This is effectively provided for are, therefore, always accessible and the fol,- -.-lo,wer may readily be dropped-to the dotted line 190811310115 indicatedxat 34 in 1 Fig. 8,

in my construction-by the'arrangement of posts 15., and'ring 14, the loweredge of which comes ,inalplane above the follower 34. The means-for adjusting the follower when it is--desirab1e*to remove or change i the packing. It is to be notedalso that the ballbearing fon the ring support is substantially in a common plane perpendicular to.

the standpipepfor which reason the relative movement'- of the top ringv 17 on its ballbearings, and in greferencej to the packing joint will havejthe most-effective possible operation. It also-to be noted that; the top ring is so 'constructed,- having reference also to the stufling box andpackinggthat neither standpi-pe water nor storm water cangetin to either the bearing-race or the stuffing box follower, the top ring thus hav-g ingthe function of a water-tight housing asrwell asof a support for the laterally extended pipe. Secured to, ring 17 by bolts '37 is a flange 38 forming a part of a cylin-.

drical extension 39; as shown in fullin Figs.

1' and 2, a gasket 40' between said flange and ring making a water-tight joint. A

v gasket" 41 between flanges .11 and 12 like wise makes a water-tight joint. above it will be apparent that the standpipe From the 10, 1 pipe13, and'section 39 are connected in water-tight relation with section 39 rotatably carried in reference to the standpipe' -.1O andrpipel3.

The section; 39 has thereon a flange 42 to which is bolted a flange 4310f, an extended curved delivery pipe 44. Preferably, the

delivery pipe .44 will be of sheet metallconnected to the wrought or "cast'iron flange member 43 by'welding, as indicated at 45' in Fig. 2. Extending through stufling boxes formed at 46 on ektension 39 is shaft 47 having arms 48 and 49 connected to the ends 7 thereof and'extending on either side of discharge pipe' 44 upwardly and outwardly from the standpipe and meetinqin a bow, asindicated at 50 in Fig. 1.

spring in a housing 52 carried by a bracketj53 ex-z;

tendingvfrom section 39 iscOnnected by a link 54 witha cross bar'55 connecting the arms 48 and 49, and bythis means;said arms and the shaft47 andparts connected there I with are heldin their normal inoperative j osition. A chain-'56 connected with how 50 is conveniently jpositioned for grasping by the. fireman or operative upon the tender of the locomotive to actuatethe arms 48 and 49 andlthe shaft 47. As shown in Fig. 2, the shaft 47 has fast thereon 'an'arm 575extending withinthe' section 39. Connected with the arm 57 by a universal or ball-and-socket joint 58at substantially the axial center of .standpipe 10 is alink-orrod '59 which ex.-

tends to" the valve mechanism,- not shown.

Upon-the delivery pipe '44; is directly su'pported a 'discharge spout 60 -o'fa type shown and described in my co-pending application SerialNumber. 134,474. vOn'the end of pipe 44 is a bail 61 which is engaged'by the hook of -the;operator anti-enables the delivery 'pipe 44 fand'qthe spout 6O thereon to-be swung .from the position parallel with the track, shown inFig..1,-to a positionextend- I ing. at rightl angles to the"- track; to either side where the v spout is operated in the manner described in -my said application to.

water the tenders of engines. It is obviousthat in the swinging of the s'pout from -the paralleltojcross-track position the" valve operating-arm 57 will, through joint 58, rotate upon link 59 which remains connected with the valve mechanism and extending through'the center 'of'standpipe 10. Thevalve can then be operated by drawing down thearms 48 and 49 through chain 56; a

To prevent the standpipe from getting out'of its position parallel with the. tracks when not in use, I provide means operable from the tender for automatically locking the discharge pipe in said parallel position. .Mounted 3 upon adjacent pairs of postsj .15, in diametrically oppositepositions, by

means of pivot pins 62 and 63 are two pairs of dogs 64 and 65 having over-balancing weighted ends 66 and 67 byv which the feet 9 j 68 and 69. ofsaid dogs are normally'held in engagement with a side each of a lug WhlCh'lTlZtY be cast directly and extended downwardly from flange 18, as indicated in dotted lines in Fig. 9,.but which preferably comprisesan ofi'set portion 171 extend ing inwardly from the toe end 70 of apiece .172 piyotally'connected at 173 with the flange 18; Plece 172 hasthereon oppositely extended arms 174,175 whichiare engaged by compression'springs 176, 177 supported.

upon 1ugs17 8, 17 9 from which extend within the springs studs 180181.

Although two pairs of dogs are provided on diametrically opposite sides of'the stand-' pipe for the purpose of permitting locking action when the laterallyextended discharge pipe comes into parallel track position extending in either direction, there is only one lug 70 and lug-carrying member 172. The

dogs 64 and 65 are held in their normal opbe seen that when the dogs are in normal po- I sition with the lug between them the flange 18, section 39, and delivery pipe 44,

' will be held locked in position and thus positioned will be parallel with the tracks in one or a diametrically opposite position. When, however, the dogs have been withdrawn from engagement with the lugs, it is apparent that upon returning the lug to locking position by rotation of the delivery pipe 44 and connected ring 17 and flange 18 the extension 171 of lug 70 will engage and ride over the surface of the dog toward which it is rotated, the other dog remaining in its position of engagement with thelower surfaceof flange 18. When the foot of the latter dog is. engaged by the lug 70, the other dog over which said lug has just ridden will return to normal position and the discharge pipe will be held automatically locked in a parallel-track position. Because of the manner in which the said lug and extensions are'held in their central position by the balanced-action of compression springs 176 and 177, it-isapparent that the checking of the momentum of rotation of the parts will be effected without shock or serious reaction which would tend to injure any of said parts, which is the principal reason for applying the pivotal spring connec-- tion of thelug rather than its integral union with the flange ring 18.

Pivoted to an'extension atthe top of ring 17 by a pivot bolt 71 is a cam piece 72 preferably in the form of a barhaving on the lower end thereof a weight 185 adjustably connected by pin-and-sl o't connection, indicatedat 186. Secured to the cam piece 72 by angle braces or suitablemeans is a cam bar 73 which overlies outwardly extended toes 74 and 75 on the lower portion of feet 68 and 69 of dogs 64 and 65, as best shown in Figs. 6, 7 and 8. The cam piece is also formed at its extremity with cam notches an abrupt end wall 76 and 77 each havin The cam notches 78 and 79, respectivef.

.76 and 77 terminate at their other ends in projections 80 and 81, which are formed at the ends of the extended cam surface provided by the lower edge of cam bar 73. An

farm 82 extends outwardly from pivot 71 and has thereon a pair of hooklike exten sions 83 and 84, either of which is adapted to be engaged by a hook operated from the tender of the locomotive to pull the cam' member to one side or the other, as may be desired.

Referring to Fig. 3 in which dogs 64 and 65 are in looking engagement with lug 70,

it is noted that the arm 82 stands vertical and the cam face 73 immediately overlies the toes 74 and 75 of the dogs. This is the normal locking position of the parts and is the position to which the parts automatically \return whenever the discharge pipe is swung back into its inoperative parallel-' track position. Then the arm or an extension thereof as 84 is engaged so as to swing the member 72 into the position indicated in Fig. 6, (or the opposite equivalent position if the member is operated from the other of two tracks on each side of the standpipe) the cam face 73 engages the toes 74 and 75 and said toes ride up the cam face successively passing over the projection 80 and into the cam notch 76. This notch, like notch 77, is so formed that when the toe 74 strikes the shoulder 78, thus preventing further oscillation of cam piece 72, the toe 75 will have just passed over projection 80 and rests upon the wall of cam notch 76, and said wall will be in a substantially hori- Zontal position, thus holding the dogs .64

and 65 correspondingly positioned so as to.

permit lug 70 to pass said dogs in either direction and allow the flange 1-8 and parts connected therewith including the discharge pipe 44 to rotate to cross-tracker operative position. In this position, the dogs 64 and 65 are not only positively withdrawn from looking position but are held'in that position and themselves operate through engagement with cam notch 76 and projections 78 and 80 to hold the cam piece 72 in. the position shown in Fig. 6 so that the dogs 64 and 65 are held in inoperative position so long as the discharge pipe and parts connected tion, and the cam piece 72 thus releasedhvili regain by gravity its normal inactive position. It will be seen that while the extended discharge pipe moves through approximately ninety degrees of annular travel in changing from its parallel-track position to the cross-track position, the locking mechanism frees itself in about one-third of this movement, thus making sure being set to relockwhen needed.

It is, therefore, only necessary forthe operative toswing the cam piece 72 into the position in Fig. 6 which can readily be done from the tender, and by engaging the bail 61 on the end of dischaige pipe 44, the said discharge pipe can readily be swung into operative position. The delivery nozzle 60 supported from discharge spout 4-1 will then be lowered into the manhole of the tender and b pulling upon chain 56 the water valve wi l be operated through arms 18, 49, shaft 47, arm 57, and link 59. After sufficient water has been delivered to the tender, the chain 56 is released, the spring in the housing 52 operating to restore the valve operating parts to initial position and close the valve.

The discharge spout is then slid back to its retracted position on the delivery nozzle-as indicated in Fig. 1 and the fireman or operative merely pushes the delivery'pipe around into position parallel with the track and the same is automatically and positively locked in said position. The operative is required only to give sufficient impetus to the discharge pipepwhich rotates freely because of its relative lightness and its ball-bearing connection with the standpipe, to certainly bring the discharge pipe to the parallel-track po- 'sition. If this impetus were enough to carry the discharge pipe beyond the parallel-track position, that would be immaterial as the automatic locking means would catch and hold the pipe when it reached the paralleltrack position and positively lock the same in that position, the parts then taking the position indicated in Figs. 1 and 3. This is because whichever way the discharge pipe is swung the lug 7O movable with flange ring 18 will engage and depress one only of either pair of dogs 64 and 65 depending upon which way the discharge pipe'is returned to initial position. The otherdog of such pair will remain in its operative position, as shown in Fig. 9 where the feet 68 or 69 thereof will be engaged by a wallof lug 7 O, or extension 171, thus bringing the rotation of the parts to a stop, at which moment the other dog will return to normal position with its foot engaging the other side wall of lug 70 or extension 171. In this manner, the discharge pipe will have been automatically and posie tively locked in its parallel-track position, from whichit cannot be moved excepting through operation of the unlocking cam piece 72, as in the manner hereinbefore described.

Having reference to Fig. 1, it is to be the fireman to rotate it.

noted that the standpipelO extendsinto a valve box or pit 100 wherein the valve casing 101 is housed and'su'pported in a well known way. The lower end of' the. standpipe rests inan annularisocket 102 shouldered at 103 andbetween the pipe and the walls of'the socket is packing 104:such as passes through a collar 105 having an annular base flange 106 which is cemented into 7 the topof the box and which has an inward annular bearing extension 107, leaving a space at 108 between the collar 105 and the standpipe 10 which is solidly filled with any desired water-proof packing material. A

water-tight man-hole cover 109 closes the entrance into the box. The valve-containing o'akum or. any other vform of packing. The standpipe' in going through the box 100 box is thus hermetically sealed against the Y entrance of'water either from the pipe or storm-water which, of course, adds to the ease of caring for the standpipe connections,

and the valve mechanism prevents any form ation of ice within the valve-contalning box and makes it easier-to prevent freezing at the valve. This is all made possible because of the fact that the standpipe 10 is permanently fixed in position, does not rotate and, therefore, can be hermetically sealed, as described or in any other equally efficient way.

The mode of operation in my improved water column has quite fully been pointed out in connection with the detailed description thereof. Its advantages lie in having very largely reduced the weight of the .extended rotatable discharge pipe and its spout and mounting and of carrying this lightened load on an efficient bearing and in coeperation with an effective water-eight joint located in the plane of the forces applied by;

mately twelve feet above rail under current operative conditions. It will readily be seen that such an arrangement greatly facilitates the ease with which the parts can be rotated as compared with those standpipes wherein This is approxi V the whole standpipe isrotated and thejoint I and bearing is from ten to seventeen feet below the plane of application of force by the operator. The engine tender is not infrequently covered with ice or from other causes presents an uncertain footing and it is im-v and the rotating member becomes relatively very light. The ball-bearing support for said member coupled with its lightness makes it rotate easily. The ease of rotation necessitates positive locking means, but such locking means (and which herein forms an important part of my invention), where entirely automatic in relocking action and easily operated from the tender of the locomotive, is an additional and positive advantage of my invention. The swinging of the discharge spout into cross-track position under influence of the wind or for other reasons, where the rotating standpipe has not been locked in parallel-track position, has long been a source of serious difliculty and has caused many accidents; and where devices have been employed for locking such constructions they have of necessity been hand operated and located close to the ground, requiring the fireman or other oper ative to be down on the ground for locking and unlocking the standpipe. The simple and eflicient support for the revoluble discharge pipe by a single row of balls and the readily accessible and effective packing and housing construction whereby the rotating joint is made water-tight are other features of advantage'of my construction, as also is the valve operating mechanism with its central link and its lever system extending outwardly in proximity with the end of the discharge pipe and having revoluble connection within the pipe with said central link.
